Determine the plane spacing in nanometers. (Please include 2 decimal places).The pupil of an eagle's eye has a diameter of 6.0 mm. Two field mice are separated by 0.010 m. From a distance of 201 m, the eagle sees them as one unresolved object and dives toward them at a speed of 16 m/s. Assume that the eagle's eye detects light that has a wavelength of 550 nm in vacuum. How much time passes until the eagle sees the mice as separate objects? t = i
